A good friend from Hangzhou recently contacted me regarding a Chinese coin he was interested in purchasing. It was a beautiful but rather expensive Szechuan coin (￥100,000 RMB or about $16,400 USD at the time of writing), and he was unsure about the deal.

The Szechuan dollar my friend was considering to buy was a high grade sample of the rare “库 not connected” variety (四川光绪剑毛龙无头车). It had sharp details and was graded AU50 by NGC, however the coin had clearly been cleaned and my friend hoped for a discount.

I browsed past sales results when I was struck by the similitude between the coin my friend coveted and a Szechuen dollar sold at the Jiuzhou 2012 Summer Auction (九州2012夏季机制币、纸币拍卖专场). At first, I thought that the coin graded XF details by PCGS had been re-submitted to NGC in a bid for a more favorable grade, but I quickly verified that the coins’ obverse were distinct.

While carefully examining the reverse, I was troubled to find an identical scratch below the right side rosette. Despite the low resolution of the pictures sent by my friend, it was obvious this ought to be a circulation mark. Two coins of the same type often exhibit wear or weak strike in the same place, but identical circulation marks should never be observed: it would indeed imply both coins were randomly damaged in the exact same fashion while being handled by countless men and women through a century!

The scratches I highlighted on the picture above were damning evidences that both coins were very high level forgeries. The counterfeiters went to the trouble of striking different obverses, but were surprisingly lazy etching the same marks on the reverse. The replica is still stunning, and actually fooled two world-class grading agencies and the highly experienced Chinese coinscollectors who bought them. It is especially troubling that without the inexplicable laziness of the counterfeiters, and a stroke of luck comparing pictures on the Internet, both fake coins would have most likely stayed undetected.

Once again, I will urge my dear readers to listen to their instinct when buying: if you are somehow hesitant about a deal, like my friend was, the best decision is often to walk away. It is also best to avoid buying cleaned or polished coins altogether, especially in high grade, as it is too convenient a camouflage for artificial aging.
